I didn't turn on I'm Under Attack mode, why are some visitors seeing a "Checking your Browser before accessing" message?

Cloudflare uses internal heuristics that may trigger the interstitial page if the requests possibly indicate a DDoS or other attack being targeted against your site. If you find that this is a false positive from a valid visitor or visitors, such as an application you use trying to reach the site, please whitelist the IP(s) in the Access Rules in your Cloudflare Firewall app.
